What's Your Limit?

Conditions on other planets are unlikely to be within the same ranges as that experienced by Earth. However, a degree of variance from ‘ideal’ ranges may be tolerable for a small number of organisms known as extremophiles. This investigation looks at the effects of subjecting a living organism (yeast) to some extreme conditions and observing changes to rates of reaction – indicating the ranges at which it can survive.

Curriculum areas covered:

• Respiration

• Cell biology

• Enzymes & rates of reaction

The video shows Chris Carr explaining the conditions that extremophiles can live in and how to perform the investigation into the conditions in which yeast can survive.
